1.下载最新源码：

https://github.com/laurenz/oracle_fdw/releases

https://github.com/laurenz/oracle_fdw/archive/ORACLE_FDW_1_5_0.tar.gz

2.设置环境变量：

ORACLE_HOME=/opt/oracle/product/11.2.0/db
export ORACLE_HOME
PATH=$PATH:$ORACLE_HOME/bin
export PATH

PGHOME=/opt/disk/241/postgres
export PGHOME
PGDATA=$PGHOME/data
export PGDATA
PATH=$PATH:$HOME/.local/bin:$HOME/bin:$PGHOME/bin
export PATH

export LD_LIBRARY_PATH=/opt/disk/241/postgres/geos/lib:/opt/disk/241/postgres/proj4/lib:/opt/disk/241/postgres/gdal/lib::$PGHOME/lib:/lib64:/usr/lib64:/usr/local/lib64:/lib:/usr/lib:/usr/local/lib:$LD_LIBRARY_PATH
PATH=$PATH:$HOME/.local/bin:$HOME/bin:$PGHOME/bin
export PATH

3.编译：

make && make install

4.创建连接

CREATE EXTENSION oracle_fdw;
grant all on foreign data wrapper oracle_fdw to postgres;
CREATE SERVER oradb_1314 FOREIGN DATA WRAPPER oracle_fdw OPTIONS (dbserver '//192.168.1.13:1521/ora');
CREATE USER MAPPING FOR postgres SERVER oradb_1314 OPTIONS (user 'username1',password 'userpass1');

5.根据字段类型对应关系创建映射表
